Bank Editor

Edit and organize all of the Evolver's 500+ stored sounds. Patch Base gives you direct access to all 4 banks, so you can organize them and back them up to files on your device.

Wave Editor

Did you know that the Evolver can store 32 user-created waveshapes for use in its digital oscillators? Patch Base gives you tools to create and edit these waves. Draw them by hand, create straight lines, randomize all or part of the wave, smooth it out, and shift or scale it. Great for creating new unique tones.
